Boss OC-3 (poly octave pedal that lets you set the range of notes to be octaves, so you can keep your higher strings dry, and add a low octave to your lower strings. I put this after my dirt pedals so the octave is fed an overwhelming signal and acts unpredictably),

JHS Colour Box (Neve 1073 console channel strip clone. This has five gain stages, I use the highest mostly for direct console fuzz sounds on “Real Love”, but the EQ section is so sensitive I can also use the clean stage to completely change my amp’s clean sound),
